Implanting and splicing articles and methods for living beings. When an implant is introduced into the interior of a body cavity mucosa is simultaneously removed from a lining of the body cavity, and the surface from which the mucosa is removed is placed in engagement with a structure for promoting the ingrowth of tissue while being immobilized with respect to this latter structure. Thus, the leading end of an implant which first enters the cavity carries an element which removes mucosa simultaneously with the introduction of the implant and which immobilizes the surface from which mucosa has been removed, the implant carrying just to the rear of the latter element a structure for engaging the surface from which the mucosa has been removed and promoting the ingrowth of tissue. In connection with splicing, the parts to be spliced are overlapped by an elongated member having a pair of spaced sets of barbs or the like for holding together and immobilizing the spliced parts, this elongated member also carrying a structure for promoting the ingrowth of tissue, and this latter structure engages the immobilized parts. Articles of this latter type may be designed either for surrounding the parts to be spliced when the latter are either solid or tubular or for being situated in the interior of the spliced parts when the latter are tubular.
In an implanting method, the steps of introducing an implant into a body cavity which is lined with mucosa while simultaneously removing mucosa from at least part of the cavity and placing in engagement with an inner surface of the cavity from which the mucosa has been removed a means carried by the implant for promoting the ingrowth of tissue.
In a method for interconnecting a pair of adjoining internal body parts in the interior of a living being, the steps of placing an elongated member in overlapping relationship with respect to the pair of adjoining parts, immobilizing those portions of the adjoining parts which overlap said member so that the adjoining parts are held together by said elongated member and are maintained stationary with respect thereto, and placing between the elongated member and the immobilized portions of said parts which remain stationary with respect to said elongated member a means for promoting the ingrowth of tissue into tight intimate contact with a surface of said elongated member, said adjoining parts being hollow and said member being of a tubular configuration and inserted into the interior of said hollow parts, and removing mucosa from the interior of said adjoining parts at the portions thereof which are immobilized prior to placing said portions in engagement with said means for promoting the ingrowth of tissue.
In a method for interconnecting a pair of adjoining internal body parts in the interior of a living being, the steps of introducing the adjoining parts into the interior of an elongated tubular member which has opposed open ends by inserting the adjoining parts into the interior of the tubular member respectively through the opposed open ends thereof until said parts are substantially adjacent each other so that the tubular member overlaps portions of said parts which are situated in the interior of said tubular member, immobilizing the portions of the parts which are situated in the interior of the tubular member by way of means carried by the tubular member so as to maintain the portions in the interior of the tubular member stationary with respect thereto, and placing in engagement with the immobilized portions of said parts which remain stationary with respect to said tubular member a means for promoting the ingrowth of tissue into tight intimate contact with an inner surface of said tubular member.
In an implant which is to be introduced into the interior of a living being, an elongated portion having an exterior surface extending between its ends and terminating in a leading end which first enters into the interior of a body cavity when the implant is introduced, said elongated portion carrying at the region of said leading end thereof a means for removing a layer of mucosa simultaneously with the movement of said elongated portion into the cavity, and means for promoting the ingrowth of tissue carried by said elongated portion at said exterior surface thereof and extending from said mucosa removing means away from said leading end so that the surface of the body cavity from which mucosa has been removed engages said means for promoting the ingrowth of tissue.
